I believe everything is possible when it comes to tech. I think it comes down to "use case". But my concern is mostly from the type of content you want to filter out.

Eg. I do not want explicit content (what I mean is pornographic content) and violence esp kids.

I respect people who want to see explicit content but I still prefer the choice to filter out content I do not want 'without seeing' it! 😬

But when I was searching for keywords in reddit is like the flood gates open! 🤦
